Problem 4 . 4 Imagine that Penn State is trimming branches from a tree. As the workers are lowering a 3 0 kg branch at a constant rate of 0 . 1 6 m s , a student cuts through the work zone so the workers suddenly stop lowering the branch. The rope ( modulus of elasticity E = 2 . 6 GPa ) supporting the branch has a diameter of 4 cm and a damping

In a diesel engine, the fuel is ignited without a spark plug. Instead, air in a cylinder is compressed adiabatically to a temperature above the ignition temperature of the fuel; at the point of maximum compression, the fuel is injected into the cylinder. Suppose that air at 2 2 C is taken into the cylinder at a volume V 1 and then compressed
